For problems such as moisture oxidation of articles, it is difficult and impractical to remove oxygen in the atmosphere, so the focus of protection must be on controlling moisture. Scientific research has proved that storing metals in an environment below the critical value of corrosion occurs, The corrosion rate is slowed down. The more the environmental humidity drops, the slower the corrosion rate. For example, if the relative humidity of the storage environment drops to 30 percent, the electrochemical corrosion process cannot be carried out due to low humidity, and the oxidation corrosion of most metals can be completely stopped.

It can be seen that, focusing on controlling the environmental moisture and controlling the relative humidity of the environment to about 40 percent, the storage safety of most items can be guaranteed. To achieve this goal, people have adopted a variety of drying methods. The traditional methods should have the following There are several methods, namely high temperature, low temperature, vacuum drying, nitrogen cabinet drying and dehumidification with hygroscopic agent. But the most widely used electronic drying cabinet is currently.

The electronic drying cabinet adopts microcomputer control to automatically identify the temperature and humidity of the environment in the box, and intelligently tracks the set temperature and humidity value. It is easy to use, directly plugged in, and can be intelligently adjusted for humidity, good dehumidification effect, low power consumption, no noise, No thermal effect, no magnetic hazard, suitable for most occasions. Generally, traditional equipment cannot achieve a stable and safe combination, and cannot effectively curb the loss caused by the influence of environmental humidity. Therefore, the drying cabinet is the most widely used in the market. Wide range of dehumidifiers.
